أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ اَلْحَكَمِ عَنْ سَيْفِ بْنِ عَمِيرَةَ عَنْ بَكْرِ بْنِ أَبِي بَكْرٍ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ إِنِّي رُبَّمَا شَكَكْتُ فِي اَلسُّورَةِ فَلاَ أَدْرِي قَرَأْتُهَا أَمْ لاَ فَأُعِيدُهَا قَالَ« إِنْ كَانَتْ طَوِيلَةً فَلاَ وَإِنْ كَانَتْ قَصِيرَةً فَأَعِدْهَا»
Ahmad ibn Muhammad from Ali ibn al-Hakam from Sayf ibn Umayrah from Bakr ibn Abi Bakr, who said:
I said to Abu Abdillah عليه السلام, peace be upon him: “Sometimes I doubt in the surah, I do not know whether I have recited it or not, so I repeat it.” Imam عليه السلام said: "If it is a long surah, then no, do not repeat it. But if it is a short surah, then repeat it."
